A particle leaves the origin at t = 0 with the initial velocity of v = (3.6 m/s)l. It experiences a constant acceleration a = -(1.2 m/s)i - (1.4 m/s)j. (a) At what time does the particle reach its maximum x coordinate? (b) What is the velocity of the particle at this time? (C) Whee is the particle at this time?
